The Charlie Fox crime thriller series by Zoë Sharp began in 2001, with Killer Instinct. In Zoë's conception of her, her protagonist is a "tough, self-sufficient heroine who didn't suffer fools gladly and could take care of herself." In the course of the series, Charlie becomes a bodyguard and moves from the north of England, where the series begins, to the United States. As Lee Child has written, "If Jack Reacher were a woman, he'd be Zoë's main character, Charlie Fox."
Felony & Mayhem publishers the first seven thrillers in the series, as well as a Charlie Fox novella (Absence of Light).
